MYC is associated with non-inflamed microenvironment in TNBC. (A) Heatmap indicating the quantified cytolytic activity of the local immune infiltrate between inflamed and non-inflamed TNBC tumors. (B) Pathological scores of sTILs and iTILs in inflamed and non-inflamed tumors. (C) IHC scores for CD8+ T cells in inflamed and non-infalmed tumors. (D) The CNV landscape of non-inflamed and inflamed tumors revealed that the largest difference between non-inflamed and inflamed tumors located in 8q24.13-8q24.3 segment (MYC). (E) The fractions of various types of CNVs of MYC in non-inflamed and inflamed tumors. (F) The comparison of copy number value (log2 copy number/ploidy) of MYC between the non-inflamed and inflamed tumors. (G) Upregulated GO terms related to MYC pathways in non-inflamed tumors compared with inflamed tumors. The data are presented as the median with IQR (B, C); two-tailed unpaired Student’s t test (B, C, F), chi-square test (E). ***P<0.001. CNV, copy number variation; GO, gene ontology; IHC, immunohistochemistry; IQR, interquartile range; NES, normalized enrichment score; sTIL/iTILs, stromal and intratumoral tumor-infiltrating lymphocytes; TNBC, triple-negative breast cancer.
